FILLING NECK AND ANTITHEFT ASSEMBLY FOR GAS TANKS 2 Sheets-Sheet 2 FiledJan. 21, 1936 Patented Sept. 1, 1936 UNITED STATES PATENT OFFICE FILLINGNECK AND ANTITHEFT ASSEBIBLY FOR GAS TANKS 1 Claim.

This invention relates broadly to gas tanks and more particularly totanks forming part of an automobile equipment for carrying gasoline.

The invention is particularly concerned with 5 means for preventingtheft, by siphoning, or

otherwise from such tanks.

Briefly the invention consists in an assembly of parts which may bereadily applied to the gas tank and which includes a filling neck forthe 10 tank together with means for efiectively preventing the siphoningof gasoline from the tank through said neck.

The invention together with its objects and advantages will be bestunderstood from a study {of the following description taken inconnection with the accompanying drawings wherein:

Figure 1 is an elevational view of the neck and anti-theft assembly, andillustrating an application of the same to a tank, a portion of which is20 shown in section.

Figure 2 is a longitudinal sectional view taken substantially on line2-2 of Figure 1.

Figure 3 is a top plan view with the cap removed.

25 Figure 4 is a fragmentary elevational view of the upper portion ofthe anti-theft cylinder.

Figure 5 is a top plan view of an anti-splash ,collar and Figure 6 is aside elevational view thereof.

30 Referring more in detail to the drawings it will be seen that inaccordance with the present invention, and in the preferred embodimentthereof, there is provided a cylindrical filling neck 5 for use with agasoline tank a. portion of which 35 is shown in the drawings andindicated by the reference numeral 6.

At its base or lower end the neck 5 is provided with an outstandingannular attaching flange 1 formed with slots 8.

40 The neck 5 is also externally threaded and is adapted to have screwedthereon as at 9 a suitable closure cap I0.

Further the invention comprises an anti-theft cylinder II which at itsupper edge has formed integral therewith upstanding lugs I2 havingreduced terminals to provide bendable fingers I3 and shoulders I4 at thejunction of the fingers I3 with the lugs I2.

Further the invention comprises an anti-splash cylinder I5 which hasprojecting from its upper edge spaced flanges I6 formed with slots I1.

Further in accordance with the present invention the top of the gasolinetank 6 is provided 55 with a filling opening 20 and inwardly from saidogening the top of the tank is provided with slots In assembling theparts herein described in detail the base flange I of the neck rests onthe top of the tank 6 with the slots 8 in the flange 5 in registry withthe slots I9 in the top of the tank 6.

The splash cylinder I5 is disposed concentric to the opening 20 and hasits flanges I6 disposed against the inner side of the top of the tankwith 10 the openings II in the flanges in registry with the openings I9.

The anti-theft cylinder II is disposed within the tank and the fingersI3 are passed upwardly through the alined slots or openings 8, I9 and I1as shown in Figure 2 and then clinched as also shown in Figure 2 to holdthe parts in the assembled relaticn shown in said figure. In thisconnection it will be understood that the assemblage will take placeduring the construction of the tank 6.

With the parts assembled as shown in Figure 2 it will be noted thatshoulders I4 together with the lugs I2 will serve to space the upperedge of the anti-theft cylinder downwardly from the top of the tank 6 sothat the gasoline entering the cylinder II will overflow through thespace between the upper edge of the cylinder II and the top of the tank6 into the tank for filling the same.

The manner of filling the tank is thought to be obvious, the gasolinebeing introduced through the neck I5 and the anti-splash cylinder I5into the cylinder II tooverflow the cylinder into the tank, cylinder I5serving not only to prevent splashing of the fluid as it is beingintroduced into the gasoline tank, but said cylinder will also serve toeffectively prevent the passage of any element into the tank 6 as mightbe efiectually used for siphoning the gasoline contents from the tank.

It is understood that after the fingers I3 have been clinched as shownin Figure 2 said fingers may be riveted, spot-welded or otherwisesecured so as to prevent any dismantling of the parts.

Having thus described the invention, what is claimed as new is:

In combination with a gasoline tank having a wall provided with afilling opening and a series of slots disposed about said opening andspaced inwardly from the edge thereof; a filling neck having a baseflange resting on the outer face of said wall, and having openings insaid flange registering with the first named openings, and an anti-theftcylinder disposed within said tank and having an open end, and alsohaving lugs projecting longitudinally from the peripheral wall of saidanti-theft cylinder at the open end thereof, said lugs having reducedends extending through the aforementioned openings in the tank wall andflange of said neck and clinched to secure said neck and anti-theftcylinder in fixed position relative to said wall, with said lugs servingto space the open end of the anti-theft cylinder from said tank wall, ananti-splash, rela- 2' a ,v I 2,052,782

tively short cylinder disposed concentric to said filling opening andprovided at one end with outstanding flanges provided with slotsregistering with the first named openings and through which said slotsthe aforementioned lugs also extend for securing said anti-splashcylinder in fixed position relative to the aforementioned parts.
